IMPROVEMENT IN FLUID-MEASURES AND PUMPS COMBINED.

Specification forming part of Letters Patent No. 1179,096, dated June'27, 1876; application tiled f May 3, 1876.

To all whom Iit may concern:

Be it' known that we, WM. H. GLARKand WM. J. CLARK, of Salem, in thecounty of Columbiana and State of Chio, have invented certain new anduseful Improvements in Fluid- Measures and Pumps Combined; and we dohereby declare that the following is a full and complete description ofthe same, reference being had to the accompanying drawings, making partof this specification, in which- Figures l and 2 are side views of theapparatus. Fig. 3 is a transverse vertical section.

Like letters of reference refer to like parts in the seyeral views.

The above said invention is a pump for drawing oil and other liquidsfrom barrels, tanks, and other vessels, and operating in connectiontherewith is a measuring device, whereby any certain fractional amountof the contents of the barrel may be obtained without the use ofordinary measures for that purpose. For a more full and completeunderstanding of the invention reference will be had to the followingdetailed description.

The pump alluded to consists of the barrel or tube A, Fig. 3, of which Bis the pumprod; C, the valve attached thereto, and operated from theoutside by a button, D. In the lower end of the pump barrel or tube A isa stationary valve, E, all of which are constructed and operated as anordinary lifting-pump, or may be.

The pump-barrel A is fitted telescopically l in a tube, F, so that itcan be extended therefrom 01 drawn therein as the depth of the barrel orother vessel may require, in order that it may reach the contents, whileby means of this device the head or measuring apparatus remaips at aconvenient height for operating it.

The tube F Vreferred to passes through the center of a receiver, G, andis secured to the top of the inside thereof, by soldering or otherwise,immediately under the stuffing-box H, Fig. 3, whereby the pump-rod ismade tight. The tube is secured in vthe bottom of the receiver by astufng box, I, into which is screwed a follower, J. It will be observed,011 examination of Fig. 3, that the tube is smaller than the diameter ofthe follower through which it passes; hence, to enlarge it, so that itmay till the follower, or nearly so, lugs aare secured to the side ofthe tube, which project so far as to reach to the sides of an overbysuspension-rods Q, substantially as shown in the drawings.

The gage-tube K may be moved up or down to obtain the requiredadjustment for measuring any desired quantity, either with the hand orby means of a screw or other well-known mechanical appliances, amongwhich the rack and pinion M N, as shown, a'ord a cheap and quick-actingdevice.

The gage-tube K, with its means of adjustment, or their equivalents, asdescribed, viz: the stuffing-box I and follower J, collar L and rods Q,rack and pinion M F, may also be attached to and used to regulate thecapacity of elevated tanks or other vessels Vindependently of anypumping device. When used, however, in combination with a pump barrel ortube, F, we prefer to have the gage-tube surround the pump-barrel, asshown, in order that greater compactness in the device may be securedthereby. A

Having described the construction and arrangement of the apparatus, theoperation of the same is as follows: The pump-barrel A F 1s extended toits full length and inserted in the tank or other vessel until the lowerend of Athe pump-barrel reaches the bottom, when by a downward pressureupon the receiver or upper section of the device the tube A istelescoped into the tube F, and the pump-barrel shortened thereby untilthe collar R rests in the bung-hole of the vessel, (or the supportprovided for it,) and the receiver is thus brought within convenientdistance for operating it; or the pun'ip-barrel may be adjusted beforeplacing it into the vessel to the proper length for withdrawing the uidwithout disturbing the sediment that may have collected in the bottom.The gage-tube K should then be adjusted by means of the rack and pinionM N, (or their equivalents, as described.) and a graduated scale, d, soas to limit the capaci-v ty of the receiver to the fractional partrequired to be Withdrawn from the contents ot' the vessel. The iiuid isthen pumped into the receiver through the openings c, Figs. 2 and 3, inthe upper end ot' the tube F, until the receiver is illed to a levelwith the top of the gage-tube K. The surplus arising from carelesspumping Will ow over the end of the gage-tube and run back into thevessel from which the fluid is being Withdrawn, leaving in the receiveronly the quantity for which the gage-tube has been specially adjusted.The

fluid thus measured may then be drawn off inl to the vessel to be filledby means of a faucet, A. When the gagetube is used in combination withan elevated tank or vessel (Whether directly connected with a pump, asshown, or entirely independent thereof) it 'may be adjusted to restrictits capacity to a desired quantity, or the upper end oi' the tube may beraised to the top of the vessel and the latter tilled full, when bylowering the gage-tube any desired quantity maybe dra-Wn oli' through itinto other vessels requiring to be filled.

Vhat We claim as our invention, and desire Witnesses:
